 The carver of the Snottsta runestone called U 329, where an Estrid and her brother Ragnfast are mentioned, is believed to be the runemaster named Fot who also made the runestones for the Jarlabanke clan.This strongly suggests that Estrid was born in Snottsta (also spelled Snåttsta), married Östen of Täby and married for the second time in Harg near Snottsta.This runic inscription is in the style Pr4 (second half of the 11th century) and it was made by Jarlabanke Ingvarsson and his brothers Sigviðr and Ingvarr in memory of their father Ingvarr and their brother Ragnvaldr.
